Extrusion includes the manufacture of lengths of cross-sectional shapes and profiles. Extruded products are available in a wide variety of materials and material combinations.
Ferrous metals and alloys are based on iron and include carbon steels, alloy steels, stainless steels, cast iron, cast steel, maraging steel, and specialty or proprietary iron-based alloys.
In the forging process, metal is shaped by pressing, pounding, or squeezing under very high pressure, to form parts called forgings. Forging processes include cold forging or heading, impression or closed die, open die, and seamless rolled ring.
Nonferrous metals and nonferrous alloys are not based on iron and include alloys of aluminum, copper, titanium, zinc, nickel, cobalt, tungsten, precious metals, refractory metals.
